Extraterrestrial organic molecules

Another idea is that amino acids which were formed extraterrestrially arrived on Earth via comets. In 2009 it was announced by NASA that scientists had identified one of the fundamental chemical building blocks of life in a comet for the first time: glycine, an amino acid, was detected in the material ejected from Comet Wild-2 in 2004 and grabbed by NASA's Stardust probe. Tiny grains, just a few thousandths of a millimeter in size, were collected from the comet and returned to Earth in 2006 in a sealed capsule, and distributed among the world's leading astro-biology labs. NASA said in a statement that it took some time for the investigating team, led by Dr Jamie Elsila, to convince itself that the glycine signature found in Stardust's sample bay was genuine and not just Earthly contamination. Glycine has been detected in meteorites before and there are also observations in interstellar gas clouds claimed for telescopes, but the Stardust find is described as a first in cometary material. Isotope analysis indicates that the Late Heavy Bombardment included cometary impacts after the Earth coalesced but before life evolved.[138] Dr. Carl Pilcher, who leads NASA's Astrobiology Institute commented that "The discovery of glycine in a comet supports the idea that the fundamental building blocks of life are prevalent in space, and strengthens the argument that life in the Universe may be common rather than rare."[139]

Based on computer model studies, the complex organic molecules necessary for life may have formed in the protoplanetary disk of dust grains surrounding the Sun before the formation of the Earth.[140] According to the computer studies, this same process may also occur around other stars that acquire planets.[140] (Also see Cosmic dust/Earth.)

Recent observations suggests that the majority of organic compounds introduced on Earth by interstellar dust particles are considered principal agents in the formation of complex molecules, thanks to their peculiar surface-catalytic activities.[141][142] Studies reported in 2008, based on 12C/13C isotopic ratios of organic compounds found in the Murchison meteorite, suggested that the RNA component uracil and related molecules, including xanthine, were formed extraterrestrially.[143][144] On August 8, 2011, a report, based on NASA studies with meteorites found on Earth, was published suggesting DNA components (adenine, guanine and related organic molecules) were made in outer space.[141][145][146][147] More recently, scientists found that the cosmic dust permeating the universe contains complex organic matter ("amorphous organic solids with a mixed aromatic-aliphatic structure") that could be created naturally, and rapidly, by stars.[148][149][150] As one of the scientists noted, "Coal and kerogen are products of life and it took a long time for them to form ... How do stars make such complicated organics under seemingly unfavorable conditions and [do] it so rapidly?"[148] Further, the scientist suggested that these compounds may have been related to the development of life on earth and said that, "If this is the case, life on Earth may have had an easier time getting started as these organics can serve as basic ingredients for life."[148]

In 2000, Jes Jørgensen and Jan M. Hollis from the Copenhagen University, reported that in the star-forming region near the center of our galaxy they found glycolaldehyde – the first evidence of an interstellar sugar molecule.[151] Then, in August 29, 2012, the same team reported the detection of glycolaldehyde in a distant star system. The molecule was found around the protostellar binary IRAS 16293-2422, which is located 400 light years from Earth.[152][153] Glycolaldehyde is needed to form ribonucleic acid, or RNA, which is similar in function to DNA. These findings suggest that complex organic molecules may form in stellar systems prior to the formation of planets, eventually arriving on young planets early in their formation.[154] Because sugars are associated with both metabolism and the genetic code, two of the most basic aspects of life, it is rationalized the discovery of any sugar in space would increase the likelihood that life may exist elsewhere in our galaxy.[151]

On April 3, 2013, NASA reported that complex organic chemicals could arise on Titan, a moon of Saturn, based on studies simulating the atmosphere of Titan.[155]

I'm increasingly intrigued by this "alien" stuff. Just even from the high number of people who claim it's true. I just feel it's wrong to not listen to people or to ridicule them when they try to tell others something they claim to be experiencing. But the numbers involved is truly astonishing.

The oracle would advise to not expect strange looking green little men, but to be prepared to face humans, extra terrestrial human beings.

Aren't we also ET eventually? think about that and the still missing never found link between primates and homo sapiens.

But Darwinism is a theory as well isn't it? We might be very similar to apes, but that's all it might be, a similarity. It also begs that question... Why are there still apes?

Is evolution a theory?

Ahh, now this brings us to the whole ''Earth was seeded by extra-terrestrials'' theory doesn't it.

ie that the human race didn't originate from Earth, and that we don't really 'belong' here...

I don't buy it. I think we developed from apes. Call me a Darwinist...

It would be interesting to meet extra terrestrial humans who are thousands of years ahead of us technology wise, maybe far in advance of us spiritually... maybe they could be benign highly spiritual people.

What if there are two distinctly different species who look alike?

Oracle wrote:
They would be recognisable as a different species, much as we can isolate humans from the other apes

Actually no, you are erring, little red cube.

Example: The Dutch grow apples, which look like apples, but these apples have Tomato genes to strengthen the skin.
Technically, it is not an apple, but a tomapple.
Now think further, if you can.

Evidence? What kind of evidence do you ask for? In the west, everything can be "proven" by some bought expertise, "proving" white is black.
